3 articles · Updated · Computerworld · Oct 16

Summary

  • 1,408 CVEs landed in Microsoft’s October Patch Tuesday—the biggest release of 2026—with 72 rated critical and CVE-2026-96951 already exploited in the wild.
  • 1,122 of the flaws hit Windows, where the exploited Shell bug bypasses Mark of the Web and can trick users into opening crafted internet-downloaded files; CISA added it to its known exploited list on Oct. 13.
  • Patch guidance puts Windows, Office, Exchange and developer tools on a Patch Now schedule, while SQL Server can follow a standard rollout because none of its 22 CVEs is critical.
  • Windows 11 updates also carry a new known issue: non-admin users may fail to open Remote Desktop sessions to devices with Administrator protection enabled, prompting Microsoft to advise testing remote access before broad deployment.
  • The release also marks multiple support and enforcement milestones, including end of support for Office 2021 and final October updates for Windows Server 2012 and 2012 R2 Extended Security Updates.
